As one can see, the adopted procedure allowed to omit the problem of
searching for a saddle by using the (inexact) minimization method which
is not always reliable [1]}, [2]}. For example, for Z=118
and N=165, the discussed effect resulting from the minimization
amounts to 0.44 MeV, which, just in this case, is quite similar to 0.46 MeV
obtained from the IWF technique; however, in Z=113 and N=163 one obtains
\(\approx 0.5\)  MeV difference between saddles obtained by both methods.
In this particular nucleus, the \(\approx 0.77\)  MeV barrier
lowering by the mass-asymmetry is the largest among all studied nuclei.
It should be also noted that for the isotopes of Z = 113 the
effect of the mass-asymmetry is particularly large, see the the top panel
in Fig. REF .
